Sarah / Elizabeth

Genesis 18:13-14
And YHWH said unto Abraham, Wherefore did Sarah laugh, saying, Shall I of a surety bear a child, which am old? Is any thing too hard for YHWH? At the time appointed I will return unto thee, according to the time of life, and Sarah shall have a son.

Luke 1:36-37
And, behold, thy cousin Elisabeth, she hath also conceived a son in her old age: and this is the sixth month with her, who was called barren. For with G-d nothing shall be impossible.

Two very similar situations, two thousand years apart, more or less . . . Now two thousand years later, still nothing is impossible with G-d.
